It appears to be from the family of machines that originated with the GE535
(and GE 645 original Multics), became Honeywell 600 series, became Honeywell
6000 series, became Honeywell Level 66, became Bull DPS8.
I can be confident of that much.

It is almost identical to the CPU control panel from the Level-66 machines I
remember except that ISTR they were black not white. 
With a better photo (higher resolution) I could confirm that it was a CPU
panel, but probably not the model number as several models shared the same
control panel.

I see on
that the CPU panel for a 6180 (Multics) looks very similar, possibly
